DOOR OR WINDOW CASING.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed February 26, 1917. Serial No. 150,924.

To all whom it may concern:

Be it known that I, OSCAR LEONARD BAX- TER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Door or Window Casings, of which the following is a specification.

This invention relates to door or window casings and has particular relation to the arrangement of parts whereby the trim structure may be rigidly secured in position without of necessity disclosing any attaching screws or bolts. In this manner, my inventionmakes for a neater appearance and incidentally,- the skill and time required for its application is greatly reduced.

The main object of my invention resides in the combination of a jamb and a trim member in connection with a toothed locking structure carried in such relation that the trim is 'securedto the jamb when the two are brought together.

Another object of my invention resides in the combination of a jamb and trim with a channel member extending longitudinally of the frame structure and designed to cooperate with a toothed locking member whereby the parts are resiliently held together and also i permanently held together after the parts have been applied. 1

The'preferred embodiment of my invention is shown in the accompanying sheet of drawings, .in which similar characters of referencedesignate corresponding parts, and in which:

Figure 1 is a fragmentary detail section shown somewhat in perspective, the view being taken through one of the side frames of the door or window structure,

. Fig. 2 is a similar view of the channel member used by me and shown detached,

and,

Fig. 3 is a perspective view of a locking member used by me. A

In Fig; 1, the building wall is represented by the reference numeral 1 and the plaster by the reference numeral 2. This wall and plaster is built into abutting relation with the buck member shown at'3 which is usually constructed of wood, in order to facilitate the ready attachment of the jamb shown at 4. In the present instance, this jamb is made of U-shape, whose legs 5 and' 6 lie contiguous with the buck 3 and are attached thereto by means of the wood screws shown at 7. Extending longitudinally of the sides 5 and 6, there is a channel member designated 8, which channel member is preferably rigidly attached to the jamb at its upper and lower ends, by means of the holes 9 and is semi-rigidly attached intermediate these ends by means of the slotted hole 10. An inspection of Fig. 1 will disclose that this channel member 8 is attached or permanently held in position by the same screws 7 which hold the jamb in position. The channel members themselves are of somewhat peculiar construction, in that their legs 11 are each provided with an inturned lip 12 and the material from which the channel member is made is sufliciently light to afford a slight resiliency to the lips 12 for the purpose of cooperatin with the locking member shown at 13. his locking member is preferably cut out as is shown at 14:, thereby forming a projecting tongue 15, which tongue is provided with a series of teeth 16 on each side. These teeth are designed to cooperate with the inturned lips 12 of the channel after the manner shown in Fig. 1. The ends of the locking member are also bent at right angles as shown at 17 and the metal from which these locking members are made is also suificiently light, so that the locking members are frictionally held in the required position within the trim members 18 because of the frictional engagement between the downturned legs 17 and the side edges 19 of the trim; In Fig. 1, these trims are shown as being provided with an inturned flange 20 along the free edge of each of the legs 19 and by means of these flanges, the locking member is locked against removal rearwardly out of the trim and because of the frictional engagement between the legs 17 and the side faces 19 of the trim sections, these. locking members'are frictionally held in their required position.

After the jamb has been set in position, the channel members are applied by means of the screws 7, which hold both the jamb and channels in their correct position. The slotted opening 10 is provided in each channel to afford a slight lateral movement of the channels should they become warped or bers are securely tions. The jambs are then applied as shown Fig. 1, wherein the teeth on the lock mg member. -13 engage the inturned lips 12 of each of the channels. Inasmuch as these channels are of material which affords aslight resiliency, these teeth will force the legs of the channel apart until their inner most position has been reached. Because surfaces 21 and the substantially of the shape of the teeth, that is, the inclined horizontal surfaces 22, the trim is permanently locked in position after once it has been applied.

What I claim-is:

1. A casing of the character described comprising a-jamb, achannel element extendlng longitudinally of said jamb' and securely fastened at its opposite ends only, a trim, inturned lips on the legs of said element, L-shaped flanges on the edges of said trim, and a fastener provided with downturned ends and a toothed tongue, said ends fitting in the spacevformed .by said L- shaped flanges and said toothed tongue engaglng said lips.

2.. A- casing of the class described comprising a jamb, trim securing means extendinglongitudinally of said jamb, fas-'-' tening elements-passing through said jamb and trim. means and serving to secure the means, a trim formed latter members in fastened relation with a wall, spaced resilient lips formed with said substantially L shaped end flanges,"a looking plate situated within said trim and retained 1n posltion therein through the re-.

siliency of said end flanges, and. a -tongue formed with said plate and provided with atter beingdisposed for engagement with the I said trim structure,

to include resilient resilient lips of said securing jamb. 3. A casing of the class described comprising a jamb, trim securi means ex tending longitudinally'of said amb, fastening elements passing through alined open ings formed in said jamb and securing means for the purpose of f the latter elements to a wall, one of said ope being elongated to permit of lateral adjust; ment of said means, spaced resilient lips' formed with said means and extending longitudinally thereof, a trim structure, ang'ularly disposed under flanges formed with a locking plate positioned 'within. said structure. and adapted to be retained in a fixed position therein by being gripped by the resilient end flanges, and a tongueprotruding-from-said plate and having notched edges,which latter be: ing adapted tobe engaged withsaid lips when said jamb and trimstructure areas-l5 sembled in cooperative relation to 'securethe same together.

4;. A casing of the "class described, comprising a jamb,. a-channel element extend ing longitudinally of said jamb, inturned '70 means to fasten said trim to said 45 resilient lips formed upon said channel element, a trim structure, end flanges formed with said structure for spacing the face of the latter from said jamb, a plate positioned within said structure, and a tongue. formed with said plate and having a plurality of notched edges, said e es being adapted for engagement with 831d. lips to' secured the trim structure in place. 7

In testimony whereof I afiix my signature in presence of two-witnesses.
